Fromensics
On-device AI
Ask about an email, answered on your device
Fromensics can use Chrome’s built-in AI, Gemini Nano, to explain its answer and to answer your questions about an email. It runs on your computer. It explains the answer; it never decides it.
What you’ll see
| Under the answer | What it means |
|---|---|
| Turn on on-device AI | Chrome can download its AI. “Chrome downloads it once. Then it explains each email you check, on this device.” |
| Chrome is downloading its on-device AI · 40% | The download is running. It will read this email when it’s done. |
| Chrome’s on-device AI is reading this email… | The AI is reading the email and the evidence. |
| Read on this device, then one line | The AI’s explanation of the answer. If it disagrees with the answer, it isn’t shown. |
Ask about this email
Every report has an Ask about this email row. Tap a suggestion or type your own question:
Who really sent this?Is this bank account new?Write a reply asking them to confirmWhat should I do?
Answers are labelled Gemini Nano in Chrome · on this device. Without the AI, suggestions still work and say Answered from the checks · on this device. Questions outside the email get “I can only answer from what Fromensics found in this email.”
A reply draft only ever goes to the address you already have for the sender. If Fromensics has no address other than the one the email came from, it says so and doesn’t draft one.
Guardrails
- Rules in code decide the answer. An AI explanation that contradicts it is thrown away.
- The AI can’t invent a domain’s age, an authentication result or a threat-list match.
- The email is fenced off as untrusted text before the AI reads it.
- If the AI isn’t available, every check still runs, and How we know lists the AI as not performed.
Turn it on
Fromensics asks once, on first run, when Chrome can download its AI: “Turn on on-device AI?” You can also turn it on later in Settings, which shows one of:
- Ready · reads what emails ask
- Downloading in Chrome…
- Not turned on yet
- Not available in this Chrome. The rules still check every email.
Questions
Does the AI send my email anywhere?
No. Gemini Nano runs inside Chrome on your computer. The email isn’t sent to Fromensics or to an AI service.
Why isn’t it available on my computer?
Chrome decides where its built-in AI can run. If it can’t, Fromensics works the same without it: the rules still check every email.
